What are the memory speeds?
There are two factors to consider regarding the speed of the memory. One is its bandwidth, meaning the maximum amount of data it can handle in one second once it gets cranking. The other is its latency, meaning how long it takes the memory module to respond to a request from the processor. The latency is described in processor clock cycles. The higher the memory latency, the more processor clock cycles the processor has to wait before the data is transferred, so the bigger the drag on processor performance. This table summarizes the memory speeds for the types of system memory (RAM) used today. GBps is gigabytes per second.
